Version Summary
Initial release

Overview

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, consists of two high-resolution digital mosaics of ice motion in Central Antarctica. The mosaics were assembled from satellite interferometric synthetic-aperture radar (InSAR) data acquired by RADARSAT-1 in 1997 and by RADARSAT-2 in 2009. See Antarctic Ice Sheet Velocity and Mapping Data for related data.

This color-coded map shows ice velocity mosaics, in meters per year, for the year 2009 in central Antarctica. Highest velocities appear in magenta and red, intermediate velocities appear in blue and green, and lowest velocities appear in yellow and peach. Areas where ice velocity is not measured appear in gray. The velocities are plotted over a digital elevation model, shown in grayscale. Credit: NASA MEaSUREs AIV Data: CSA
